Chapter 5 Remote Interface Reference

Simplified Programming Overview

Example: Using CONFigure With INITiate and FETCh?

The following program segment is similar to the previous example but it uses INITiate to place the instrument in the “wait-for-trigger” state. The INITiate command places the instrument in the “wait-for-trigger”

state, scans the specified channel when the R terminal is pulsed on the rear panel, and sends the reading to reading memory. The FETCh? command transfers the reading from reading memory to the instrument’s output buffer.

Storing readings in memory using the INITiate command is faster than sending readings to the output buffer using the READ? command. The INITiate command is also an “overlapped” command. This means that after executing the INITiate command, you can send other commands that do not affect the scan. Note that the FETCh? command will wait until the scan is complete to terminate. The instrument can store up to 50,000 readings in internal reading memory.
